摘要：Low gain feedback refers to certain families of stabilizing state feedback gains that areparameterized in a scalar and go to zero as the scalar decreases to zero. Low gain feedback was initiallyproposed to achieve semi-global stabilization of linear systems subject to input saturation. It wasthen combined with high gain feedback in different ways for solving various control problems. Theresulting feedback laws are referred to as low-and-high gain feedback. Since the introduction of lowgain feedback in the context of semi-global stabilization of linear systems subject to input saturation,there has been effort to develop alternative methods for low gain design, to characterize key featuresof low gain feedback, and to explore new applications of the low gain and low-and-high gain *** paper reviews the developments in low gain and low-and-high gain feedback designs.

摘要：The secure socket layer/ transport layer security(SSL/TLS) handshake protocol uses public key cryptographic algorithms such as RSA for key establishment. Typically, public key cryptographic algorithm is computational intensive due to the modular multiplications. Therefore, SSL/TLS servers often become swamped while performing public key decryptions when the simultaneous requests increase quickly. A batch RSA decryption algorithm was proposed. The novel algorithm provides the reasonable response time and optimizes server performance significantly. The decryption speedup is proportional to the batch size 6, for instance, the speedup factor is 4, while in Shacham's scheme the acceleration rate is only 2.5 when 6 = 4.

摘要：A new algorithm for the solution of under constraint graph in sketch drawing is put forward. The directed process of constraint graph is completed by picking concealed constraints of adjacent entities in sketch of few or no dimensions. In this paper, the priority of concealed constraint is given by the different constraint types and constructing orders, and some more priority concealed constraints are forced into obvious ones by the need number of constraint for every node in constraint solution process.

摘要：非接触式传感器相比接触式触觉传感器可以避免与物体直接接触过程中产生的噪声,因而能够获取更有价值的原始数据表征物体内在属性;然而针对非接触式传感器感知的物体属性数据而言,现有算法难以实现单样本学习下的物体准确识别.为解决这一问题,本文提出一种新颖的单样本学习下时序约束稀疏表示方法(one-shot learning with temporally constrained sparse representation,OSLTCSR)用于识别5种不同材料下的50个物体类别.首先将两种原始数据(Lumini光谱和SCiO光谱)并行投影至共享子空间,并且使用聚类典型关联分析法(cluster canonical correlation analysis,C-CCA)计算两种原始数据的聚类相关性特征;其次通过稀疏表示分别计算得到聚类相关性特征数据以及原始数据的编码向量,并利用原始数据的编码向量对相关性特征数据的编码向量进行二次投影映射;然后将两次映射后的原始数据和相关性特征数据进行重构,以充分耦合化两种光谱数据,解决了单样本学习下的数据稀缺问题;进一步地,设计新颖的时序约束稀疏表示方法计算重构后的原始数据和相关性特征数据,以充分考虑每个光谱序列的时序特征;最后与最新的物体识别方法进行实验对比,结果表明提出的OSL-TCSR方法提高了单样本学习情况下的物体识别结果.此外,OSL-TCSR还可灵活迁移至多种应用场景,比如材料识别或纹理识别等.
